Hundreds of people have gathered on an Adelaide beach to protest against Norwegian energy giant Equinor's plans to drill in the Great Australian Bight.
Attending the Hands Across the Sand protest, Greens Senator Sarah Hanson-Young says the majority of South Australians don't want any oil drilling in the Great Australian Bight.
"We don't want oil washing up on our beautiful beaches and we know, in an era of climate change, we just can't afford to be expanding oil drilling or coal mines or any other fossil fuels," she said on Sunday.
Equinor, who says the Bight "could be one of Australia's largest untapped oil reserves", wants to drill a well more than 370km off the coast of South Australia.
Drilling of the proposed Stromlo-1 well will begin in the summer of 2020/21 if it receives all necessary regulatory approval.
Ms Hanson-Young says the potential jobs gained from the proposed project is "not worth the risk".
"What we know is that the jobs from the fishing and tourism industry would be put at risk if there was an oil spill."
Equinor in February voluntarily released an environmental draft plan, which was open to public feedback over a 30-day period.
Last month, they updated their plan and submitted it to the environmental regulator for offshore petroleum safety.
The South Australian director of environmental advocacy group Wilderness Society, Peter Owen, said there are "unprecedented levels of community concern" over the project with nearly 20 councils in opposition.
"It's very remote where they're proposing to drill, so if it all goes wrong out here, there's nothing they can do.
"We all remember the Gulf of Mexico," Mr Owen said.
Coalition campaign spokesman Simon Birmingham said he trusts the environmental regulation to make the right call on whether the project goes ahead.
"There are a large proportion of constituents who want to see jobs and opportunities created, as long as there's no environmental harm," Mr Birimingham told reporters in Adelaide on Sunday.
